I 've read the poem thoroughly several times. IMO, Kangxi was still a confucianist , at least in a confucianist or buddist thoughtway and write down such a poem. I can feel. Ok, all of you can examine it carefully.
Since I have TaiE's ok, here is a small attempt at translation. I did not try to make my translation poetic, just give a account of the meaning. Somechineseperson, it would be interesting if you could give a number of details on when and how it was composed...
My first (and non chinese, obviously) impression is that it looks like some kind of summary of christianism. I don't think any comparison with other religions is done, and even though one can feel Kangxi's interest, I think it is far from a declaration of faith.
Without beginning or end, he who first created shapes and sounds is the True Lord.
Showing universal compassion and justice, he proclaimed and explained his laws.
Everywhere, all the things that our eyes can see around them, we must now they were created by his works
His body is one, with no beginning nor end, but he stands as three, neither quiet not empty
The paradise on earth was long ago close to the first man, but the ways to Heavens was reopened by the son of God.
Refusing the extraordinary, straightforward and without fear, how can the True Doctrine not be admired by everyone?
Through his deeds, the blood spillt on the cross became a river, and many person set from the west to tell of his mercy
While he was taken to the tribunal in the middle of the night, his disciple betrayed him three times before the rooster had sung twice
Five thousand whips broke into his skin, he was hung six feet wide between two bandits
To the sorrow of everyone, once he had uttered seven words, his souls escaped from his body.
The door to Heaven was close by the first man, but the road to bliss was reopened by the son of God.
If I honestly receive the spirit, God and the son, my children will receive the grace (illumination) and share eternal life.
Now, some of these translations are probably very wrong, as usual comments are welcome.
